It used to be written in the solarisinternals.com wiki - but I can't  
seem to find it anymore.

ZFS is a moving target, in some ways, so the requirements may have  
changed or are no longer that simple.

But it made sense in the early days, when SUN's thumper (X4500, 2*DC  
Opteron, 48 disks, 16 GB RAM) more or less fit the requirements  
perfectly.


cheers,
Rainer
